It is the end of an era.
George Eads, the last original cast member of CSI, will be exiting the long running series at the end of season 15. As reported by TVGuide.com, his exist will involve Gig Harbor Killer case. At the time of this story, it’s unclear how that will unfold.
There is a history of Eads leaving the show for brief hiatuses. In 2013, he left for a short period of time after a conflict with one of the shows’ writers. Also, in 2004 co-star Jorga Fox and Eads were both fired from the show briefly after salary disputes.
